This is easy. I bet you can figure out the answer yourself! A mountain is a mass of land that is taller than its surroundings. I don't think there is a definition for how high a mountain should be, but I would guess anything less than about 1000 ft higher we would probably call a hill. So a mountain is some high piece of land. One way to make a mountain is to have a volcano erupt, but most mountains on Earth aren't made this way.
Most mountains are made by the collisions of thick portions of the Earth's skin. We call the upper part of the crust and the upper mantle a PLATE. The Earth has about a dozen plates that move slowly sideways, bouncing into each other and sometimes sliding down under one another. During many of the plate collisions part of the Earth's crust gets shoved up into the air creating mountains. All of the major mountain chains - such as the Rockies, the Himalayas and Alps - were made this way. Without plates there would be far fewer mountains.
So, volcanoes are mountains, but there are many mountains that are not volcanoes!

You may have mountains that were or are being formed by volcanic action. Or you may have mountains that are formed by the movement of Earth's tectonic plates. Volcanic mountains form very rapidly and spectacularly, when lava bursts through the Earth's crust and is ejected onto the surface often after causing a large bubble far underground which raises the surface crust high into the air, compared to those formed by tectonic plates, the movement of which causes upheavals of the surface as one plate moves beneath another. Likely billions of years ago these movements were much faster than today. Mt Everest is still growing about 1/4" per year due to this type movement.

Mountains can be formed through various means, one such mean is volcanic activity. Not all mountains are Volcanos.

volcanos burst and emit lava , a hot fire fluid. But mountains do not. thats it.
